# Applied Maths Seminar: Rogers -- On a Novel Class of Nonlinear Elastic Materials

DATE: Wednesday, May 9
TIME: 2:00pm
LOCATION: University of Sydney, Eastern AvenueLecture Theatre (Level 1)

Abstract:

A class of infinitesimal B\"acklund transformations is used to construct model
constitutive laws for which the nonlinear system describing uniaxial wave propagation
may be reduced to a canonical form associated with Hookean response in an asymptotic
limit.  The stress strain laws are given parametrically in terms of elliptic functions.
Importantly, these models can allow a change in concavity in the stress strain law.
